  • Patent number: 7765361
    Abstract: To ensure that logs representative of data changes are durably written, localized storage media cache is flushed to force a write to stable storage. Log sequence number tracking is leveraged to determine if log data in a localized storage media cache is likely to have not been written to durable storage. When this condition is likely, a FLUSH_CACHE command is issued to a storage media controller to force a durable write. This allows recovery of data changes to a transactional system even when its associated storage media does not provide write-ordering guarantees. Moreover, flushing of the storage media cache can be accomplished at a frequency that provides an upper bound on a maximum time between a transaction commit and data being made durable.

  • Patent number: 7577291
    Abstract: A color defined by a chroma point and by a luma value is adjusted by defining a reference chroma point and shifting the chroma point towards the reference point if the chroma point is within a predefined tilted rectangle in the chroma coordinate plane that encloses the reference point; or if the chroma point is within both of two predefined polygons, in the chroma coordinate plane, that enclose the reference point; or if the luma value is within a predefined luma range. Preferably, the two polygons are a rectangle and a rhombus. The chroma point is shifted using a continuous shift function that vanishes on the rectangle and on the rhombus.

  • Patent number: 7512269
    Abstract: The contrast of a digital image is enhanced by forming a histogram of the luma values of an active area of the image, computing “initial” bin indices that partition the histogram into bins of substantially equal population, mapping the “initial” bin indices into “final” bin indices that are more uniformly spaced than the “initial” bin indices, and adjusting the luma values of all the pixels in accordance with the “final” bin indices.
